LAHAINA, Hawaii -- Here are some observations from the second day of the EA Sports Maui Invitational.

After dominating Mississippi State on Monday, the North Carolina Tar Heels got a rude wake-up call versus Butler on Tuesday. On Monday evening I wrote: “North Carolina has much more talent, but the Bulldogs are scrappy and well-coached. The Tar Heels are more of a finesse team. The physicality of Butler could give the Heels problems.” That’s exactly what happened. North Carolina was outrebounded 36-27 and Butler beat them to just about every loose ball.

After the game, North Carolina head coach Roy Williams admitted that he had the better players, but Butler and coach Brad Stevens had the better, tougher team. “They were more physical, more assertive and more aggressive,” Williams said. “They're really good. Brad's clubs are really intelligent. I like their toughness and their intelligence more than their talent, and I'm not trying to put down their talent. But I love their toughness and their intelligence.”

UNC clearly has the talent, but does anyone on this team have the toughness the Heels needs to go deep?

Sixth man P.J. Hairston was, for the second night in a row, the best and toughest Tar Heel on the floor. It might be just a matter of time before Williams puts him in the starting lineup.

Most disappointing was forward James Michael McAdoo. In the tourney-opening blowout against Mississippi State, McAdoo was solid on offense, but had four mind-boggling turnovers, prompting Williams to comment after the game that “we can’t throw the basketball around.”

On Tuesday night, McAdoo had seven turnovers to go with his 10 points and five rebounds. Williams isn’t the only one miffed by the performance of his big man.

Most of the NBA scouts and general managers in the audience savaged McAdoo for his performance the past two games. “He looks good in a basketball uniform,” one GM told me. “But after that, I’m not sure what I’m supposed to like. He’s a pretty good athlete, but he isn’t very skilled and he doesn’t go hard all the time. There’s not one thing he does that really stands out about his game. He certainly hasn’t played like a top-five pick.”

McAdoo is currently ranked No. 6 on our Big Board -- but could be in for a drop if he doesn’t start picking it up.

Illinois continued its impressive run in the tournament with an 84-61 win over local underdogs Chaminade on Tuesday. The Illini got balanced scoring -- Brandon Paul scored 13 points, D.J. Richardson had 11 and Joseph Bertrand 14. The Illini are off to a 5-0 start, but they haven’t really been tested yet. Butler should give them everything they can handle and will be the favorites to win it all after dominating North Carolina. But don’t count out Illinois. The team is playing with a lot more aggressiveness and discipline under new head coach John Groce. It has a terrific backcourt in Richardson, Paul and Abrams and size up front.

A win in the tournament will be a huge boon to the Illini's confidence. They aren’t in the same class as Big Ten elite teams such as Indiana, Ohio State, Michigan or Michigan State, but they, along with Wisconsin, Minnesota and Iowa, may be a very tough outs in the league. I won’t be surprised if the Big Ten gets eight teams into the NCAA tournament this season.

A number of my tweeps laughed at me Monday when I said that NBA scouts were intrigued by Butler freshman Kellen Dunham. I don’t think they are laughing anymore. Dunham bounced back from an awful game versus Marquette and really put the dagger in the Tar Heels in the second half. He ended the game with 17 points and was 5-for-9 from beyond the arc. He’s still a little tentative and passed up a few open shots in the game, but his stroke is flat-out pure. Dunham isn’t your average mid-major guard. He was ranked as a top-100 player by ESPN and was an NBA camp invitee. Dunham isn’t a one-and-done prospect, but as he continues to get stronger and more confident, he could have a future in the pros after his junior or senior years of college.

The Texas debacle continued Tuesday with a 59-53 overtime loss to USC. The good news? The Longhorns didn’t get blown out this time and played with more urgency. The bad news? Offensively this team is just a mess. When (or is it if?) the Longhorns get Myck Kabongo back, they’ll be better. But I don’t think he has the talent alone to turn things around. There just isn’t a lot of talent around Kabongo. Sophomore Sheldon McClellan has struggled in Maui, going just 8-for-25 from the field and 1-for-11 from 3. Freshman big man Cameron Ridley was ranked as the eighth-best prospect in the country by ESPN, but he’s looked out of shape and overwhelmed in the early going.It could be a long year, Texas fans.

Marquette fans, meanwhile, are hoping they have found a go-to scorer in junior Vander Blue. For the second consecutive game, Blue led the team in scoring with 18 points and three assists versus Mississippi State. Blue has always had the talent, but he has struggled with consistency and aggressiveness in the past. What’s different this year? “I'm just playing with a free mind and just playing off my teammates,” Blue said. “Junior [Cadougan] is a great guy, and everybody's going to double Davante [Gardner], so that pretty much leaves me open for shots. So I feel like if I'm making those shots, our team is a much better team. I'm not trying to do nothing that we don't do every day in practice.” Blue’s versatility, toughness athleticism and defense all intrigue NBA scouts. If he can show some offensive prowess as well, he could be a second-round pick.

There was a moment in time when USC big man Dewayne Dedmon was considered a potential NBA prospect. That time has probably passed. Dedmon has the size and athletic ability to be a pro. But he has no feel for the game. That’s always a problem, but it’s an even bigger problem when you’re already 23 years old. Dedmon had 8 points, 8 rebounds and 3 blocks against Texas but was just 3-for-11 from the field.

Butler will face Illinois in the EA Sports Maui Invitational Final on Wednesday at 10 p.m. ET on ESPN. North Carolina will play Chaminade in the consolation game at 7:30 p.m ET on ESPN2.
